APPARATUS FOR AUTOMATIC SIGNALING ON RAILWAYS.

SPECIFIGATION.forming part of Letters Patent No. 523,424, dated July 24, 18945 Application filed January 1'7, 1394- Serial No. 497,187. (No model.) I

To alltohom, it may concern:

Be it known that I, HENRY FRosrCLaRK, a citizen of the United States, residing at Easton, in the State of Pennsylvania, have invented a new and Improved Apparatus for Automatic Fog Signaling on Railways, of which the following is a specification.

My invention has reference to an improved apparatus for automatic fog signaling on railways. In previous efforts in this direction, apparatus has been devised for operating with the signal connection for the distant or home signal, or any signal, so that the detonator is in position on the fail when the signal is in the danger attitude and is removed therefrom when the signal is deflected to the safety attitude.

With my apparatus I arrange that it is antomatic. in action and that a detonator is exploded irrespective of the-position of the signal arm, that is to say, that the first wheel of the engine explodes the detonator and the apparatus works that no second explosion takes place unless desirable, for instance, it is 00- casionally desirable to have two explosions, but, immediately the last vehicle passesover the apparatus it automatically places another torpedo in position to be exploded.

In order that my invention may be better understood I will proceed to describe the drawings hereunto annexed.

Figure 1 illustrates a cross section' of my apparatus with only a portion of the detonatorl tube shown the portion not shown is simply a continuation of the tube and spring. Fig. 2 illustrates a section A-A Fig. 1. Fig. 3 is a part plan of Fig. 1 with the magazine tube removed and the cover on the left hand side also removed. Fig. 4 is a View showing the method of connection to the rail and alsoillustrating the spring underneath the anvil for allowing forworn tires. Fig. 5 is a plan of Fig. 4 with the top of the rail removed,

' showing the method of clipping the web. The

magazine 1. is not shown in this figure. Fig. 6 illustrates an enlarged View of the connection a: to the lever b viewed from the front of the rail. This illustrates the spiral spring e referred to hereinafter. Fig. 7 is an enlarged View of the lever 19 and the top brake 'r on the B+-B of Fig. 1, looking toward the end of the machine away from the rail. Fig. 10 illus- 7 UNITED S- Ares PATENT OFFICE. 2

trates the slide or torpedo carrier for carrying the torpedoes from the magazine under the exploder or hammer. Fig. 11 is a side view of the brake j. Fig. 12 is a plan view of Fig. 11, partly insection, showing the spring at the termination. Fig. 13- is a plan view partly in section showing the cog Wheels and I the connection from. the crank 0, which connection works in slot 19 Fig. 1. Fig. 14 is an elevation of the cog wheels. Fig. 15 shows the rail and a sectional view of the lifting bar k; said bar is lifted automatically above the rail to be in contact for the tread of the wheel, by the spiral spring is held in each clip. Fig. 16 is aside elevation of the lifting bar and clip. I

The same letters and numerals refer tothe same parts in the several figures of the drawgs- 0,, Figs. 1, 2, 3 and 4 is the hammer or exploder, which when the machine isready for explosion stands half an inch above the rail and is forced down by the first wheel of the locomotive which strikes it, exploding the torpedo under it and raising the lever.

12, Figs. 1, 2, 3, 6, 7, 8 and 14 which is at- 'tached to the hammer on by the bolt c'Fig s. 1. 2, 3, 4, 7 and 8 and pivoted at (1 Figs. 1, 3, 4,

7 and 8, compressing the spiral spring 6 shown in Fig. Sandlifting the presser f Figs.

1, 7, Sand 14 attached to the lever Hey the bolt g bringing it to bear on one of the nine bolts in the gear wheel h Figs. 1, 13 and 14. The presserj'is provided with a spiral spring 1' shown in Fig. 7, when the presser is raised Y to the position shown in Fig. 1 the spring by its bearing against the under side of the lever over the bolt b pushes the presser forward in the gear wheel h. h

The machine is now ready to load itself for the next train,but by the means of the brake j Figs. 1, 3, 6, 9, 11 and 16 it is held in this position while the train is passing, operated by .an automatic lifting bar is, shown in Figs. 1, 3, 11,12,15 and 16. As soon as the .train has left, the bar is moved to its position shown by the dotted lines in'Fig. l6 drawing with it the brakej from the friction wheel Z Figs. 1, 13 and 14. The lever is now drawn down by the spiral spring e, and by the presser f the 45 oted together bythe pin 23.

gear wheel h is moved sufficient to change the position of the bolts in the same one point,

imparting to the second gear wheel on Figs.

1, 13 and 14 one revolution, when the lever is 5 stopped from further movement by coming in contact with the cover of the spring barrel n shown in Figs. '1, 3, 6, 9, 13 and 14; to the axle of the second gear wheel m is atta'cheda crank 0 Figs. 1, 3 and 13 and traveling in the to slot of the slide attachment 19 Figs. 1, 3,

and 13, one half its revolution draws the slide q Figs. 1, 2, 6,9 and 10 back to the magazine 25 Figs. 1, 3, 4, 6 and 9 to receive another torpedo and the remaining half of its movement pushes the slide forward moving with it the torpedo under hammer a. To the lever b at its rearisattached an arm r Figs. 1, 7 and 8 provided at its rear with an adjusting screw to come in contact with the friction wheel Zwhen the lever b strikes the cover of the spring barrel it thus stopping further movement of the wheel. Tlo the friction wheel Z are attached fans Z to regulate the speed.

The brake j is provided with a spiral spring j to hold the machine from reloading with more or less movement of the lifting bar is.

Theattachment of the machine to the rail is plainly shown in Figs. 4, 5, 15 and 16. The workingparts are all inclosed from waterand dust and the machine is calculated to run without on.

'lhetorpedoes are forced through the magazine by a spiral spring 15' shown in Fig. 1. By removing the bolts 2; Figs. 3, 4c, 5, 6 and 3 5 9 the top part of the machine can be taken off and with it the slide and all other moving parts.

When the machine is not required it is thrown out of function through the lifting bar 70 being held below the top of the rail by turning a button, Figs. 15 and 16, marked 2. The bar [6 has a link 21 pivoted to it. Another link 22 is pivoted to the bracket which supports the bar is, and the two links are piv- A bar 24: is also connected to the pin 23 so that the bar 70 may be operated from a distance. The but ton a (Fig. 16) has a projection on one side, which bears against the link 21 when turned to the right, and thereby holds the bar 70 depressed.

- When an unexploded torpedo is in position, in the detonator, to give the danger signal to the next train, the said torpedo should be removed before turning the button, if it is desired not to give the-danger signal to the next train.

Having fully described my invention, what I claim, and desire to secure by Letters Pat- 69 out, is-- 1. In a detonating signal, the combination, with the hammerarranged to be depressed by a front wheel of the train, of the pivoted lever 12 connected to the hammer at one end i and provided with the presserf at the other, the wheel It provided with pins arranged in the path of the presser, the crank o operatively connected with the wheel h, the slide q operatively connected with the said crank, a torpedo magazine arranged over the slide 70 q, and a spring operatively connected to the lever 0, whereby a torpedo is placed under the hammer by the slide q, substantially as set forth.

2. In a detonating signal, the combination, with a hammer arranged to be depressed by a front wheel of the train, of the pivoted lever 79 connected to the hammer at one end and provided with the presser fat the other, the toothed wheel h providedwith pins ar- 8o ranged in the path of the presser,the toothed wheel m operatively connected with the toothed wheel h, the crank o driven by the wheel on, the friction wheel Z operatively connected with the wheel m, the slide q provided with the slotted attachment p engaging with the said crank, a torpedo magazine arranged over the slide q, a spring operatively connected to the lever 12, and a brake arm/1* attached to the lever 72 and caused to press on go the wheel Z by the said spring when atorpedo has been placed under the 'hammer,substan tially as set forth.
